FENCE MACHINE.

Application filed March 7, 1925. Serial No. 13,728.

This invention has to do with improvements in machines for manufacturing fencing of the type in which vertical pickets are connected together by a series of longitudinal strand wires. Fencing of this kind is used for many purposes including the fencing of yards for chickens, and other domestic animals, etc.

The main object of the invention is to provide in machines of this type mechanism for trimming the ends of the pickets so as to point them and finish them.

In connection with the above, it is an object to provide means for pointing the pickets after they have been joined together in the continuous fence.

Machines capable of accomplishing this general result have heretofore been, pro vided as, for example, that disclosed in Letters Patent of the United States No. 1,3 l0,- 530 issued to me May 18, 1920, on my application filed March 17, 1919. The type of machine therein disclosed includes knives for pointing the end portions of the pickets by a movement transverse to the pickets mechanisms which, in some cases, cannot be conveniently applied to the fence machine proper.

The main object of the present invention is to provide means for pointing the pickets by the use of cutters which are movable lengthwise of the individual pickets as distinguished from the transverse movement F of my earlier patent.

Another object in connection with the above is to provide a very simple construction of mechanism for accomplishing the above result and one which will be very positive in its operation.

A further object is to provide a pointing mechanism which can be very conveniently and readily applied to picket fence machines of the construction and arrangement already in use.

Other objects and uses of the invention will appear from a detailed description of the same, which consists in thefeatures of construction and combinations of parts hereinafter described and claimed.

In the drawings:

Figure 1 shows a plan view of the machine embodying the features of the present invention;

Fig. 2 shows a vertical elevation on the line 2-2 of Fig. 1, looking in the direction of the arrows and on enlarged scale;

Fig. 8 shows a fragmentary plan view of the picket pointing mechanism with the other portions of the machine removed, and on enlarged scale as compared to Figs. 1 and 2, the ends of some of the pickets being broken off, and the pointing mechanism standing in the idle position;

Fig. 4c shows an elevation on the line 44 of Fig. 3, looking in the direction of the arrows;

Fig. 5 shows a fragmentary vertical section on the line 5-5 of Fig. 4-, looking in the direction of the arrows, but on enlarged scale;

Fig. 6 shows a view similar to that of Fig. 3, with the exception. that the cutting jaws have been forced forward so as to trim the edges of the end of the picket to point the same;

Fig. 7 shows on enlarged scale a frag- -mentary view of the cutting jaws in the themselves and involves the use of certain position of Fig. 3;

Fig. 8 shows an elevation corresponding to Fig. 7 and Fig. 9 shows a fragmentary elevation of the pull-oft mechanism.

I will now describe the construction and mode of operation of the particular fence machine illustrated in the drawings and to which I have shown the features of the present invention as being applied, since machines of this type are well known and their operation well understood in the art. Moreover, this type of machine is also shown and described in the drawings and specification of the aforesaid Patent No. 1,340,530. particular machine illustrated the pickets are fed in from the position 9 of Fig. 1 and travel towards the observer, eventually occupying such positions as those of the pickets 10 and 11 of said figure. The individual pickets are then fed sidewise towards the left to the general position of the picket 12 of Fig. 1, and at the same time the pairs of longitudinal strand wires such as 13 are twisted about the picket in proper spaced relationship. The completed fenc- I will, however, state in the ing l5 then drawn away from the ohszerrer towards the position 1t of Fig. 1.

The pickets are initially nnpointed and have squared ends at both code. it is the main object of the present; invention to pro vide mechanism for pointing the rockets.

This; malow it poi-sihle tor the hladea to perform their cattle;- operation at the same time that: the tearing in being advanced toward the ielt. :so that the rotting operation can be perill) lfltl formed in a machine for the continuous manufacture of fencing.

A spring 49 is being provided for drawing the blades 22 and 23 and connected mechanism back to the initialposition after the cutting blades are dropped away from the picket, such initial position being established by a stop pin 50 on the bar 2st.

The fencing may be drawn off in any convenient manner, but the pull-off mechanism illustrated in Fig. 9 is a convenient one to use. The same includes a pulling drum 51 preferably comprising a series of plates scoured across a shaft 52 which revolves in a definite relation to the balance of the machine. A series of angle bars 53 extend across and are secured to the edges of these plates. These angle bars are spaced at the same spacing as he pickets of the completed fencing. Such angle bars are also notched to receive the longitudinal strand wires 13 so that the pickets can lie between the angle bars as clearly evident from F 9. With this arrangement the drum 51 will serve as a very satisfactory tension drum for drawing the fencing toward the left.

An idle roller serves to deliver the fencing to the drum 51, and another idle roller 55 serves to deliver the fencing from the drum 51 to a winding drum 56. The drum 5G is preferably driven by a chain 5'? from a suitable power shaft. A slip connection, such as a clutch 58, is established between the power shaft and the chain 57, so that as the fencing winds upon the drum 56 and the diameter increases, the clutch can slip suiiicicntly to compensate for such increased diameter.

It will be Seen from the foregoing, that in tlii present machine I have provided means for trimming the end portions of the pickets by a cutting operation parallel to the length of the picket-s as distinguished from previous constructions in which the cutting operation has been by a movement tra sverse with re .spect to the picket.

lVhile I have herein shown and described only a single embodiment of the features (if the present invention, still I do not intend to limit myself to the same, except as I may do so in the claims.

I claim: 7

1. In a machine for the manufacture of picket fencing, having cross pickets together with longitudinally extending strand wires joining said pickets together, the combination of means for continuously advancing the fencing in the direction of the strand wires, a frame bar mounted for movement towards and from the line of travel of the pickets of said fencing, a pair of cutters on said frame bar movable parallel to the length. of the pickets, means for raising the frame bar to present the cutters at the sides of a picket, and means for moving the cut-- ters longitudinally of the picket to thereby trim the sides of the picket, substantially as described.

2. In a machine for the manufacture of fencing having transverse pickets and longitudinally extending strand wires, the combination of means for continuously advancing the fencing in a direction parallel to the strand wires, a blade carrier, means for moving the same towards and-from a picket while the fencing is moving, and means for moving the blades longitudinally of the picket while the fencing is moving to thereby trim the sides of the picket, substantially as described.
